Animals are bred for a purpose!
The majority of animals in the Uk are forcibly bred against their will. This is fucked up. Humans should not be forcing themselves inside non-human animals so they can eat them or make money from them. It's mental. Also part of the breeding involves getting semen from males. The whole process is fucked up and unnecessary. Some people even label the artificial insemination process as raping the female cows. And even sexual abuse of the males when they jerk them off.
The use of the word 'purpose' is flimsy and baseless. Humans are arbitrarily assigning a 'purpose' to these individuals against their will. Cats and dogs are bred in Asia for food, is this their purpose? Some humans are forced into prostitution, is this their purpose? 'Purpose' is just a cop out word and an excuse to abuse others.
Humans can live on a Vegan diet, so don't need to exploit animals. It's just another excuse non-vegans use to justify them being too lazy to change or not caring about the fact they are harming others.
